Answer: Very low!
Last week I attended a one-day course in mobile UX. The course was very basic and just useless for me. A lot of it revolved around the fact that people hold iPads with 2 hands and iPhones with 1 hand and they use them in different environments. Nothing technical was ever discussed. I do not recommend to anyone already working in Marketing, Design or Web Development. Probably very useful for C-level management that doesn't have a clue.
One of the fellow attendants was from the University of Nottingham (I'm not 100% sure this was the name of the university but I believe so). He explained that he is attending a series of trainings with this company, learning about web development, so he can then teach this subject at the university.
I was utterly confused when I heard this, I refused to believe it. I cannot imagine the quality of this course when this man starts teaching it after just a series of basic trainings... I thought there's some legal requirements about who can teach what, obviously I've been wrong.
Too bad for the poor bloke who enrolls into this future course with the University of Nottingham, which by the way is ranked #75 in the world.
